CUTTER FOR FLOOR-CLOTHS, 86C.

SPECIFICATION forming part of Letters Patent No. 625,550, dated May 2 3, 1899.

A li ation fil d February 3, 1899. Serial No. 704,422. (No model.)

To aZZ whom it may concern:

Be it known that we, LEE H. GEISENDORFF and ALBERT M MAGUIRE, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Cutters for Floor-Cloths, Linoleums, &c., of which the following is a specification.

The object of our said invention is to produce a device whereby all kinds of floorclothssuch as 0ilcloths, linoleums, &c. may be quickly and easily bisected, thereby overcomin g the difficulty now encountered by using a knife or the like, which is tedious, as well as laborious, especially when the strip of cloth is of considerable length. By the use of our invention, however, a means is provided whereby these difficulties have been overcome.

There are other features that will be hereinafter more particularly described and then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof and on which similar numerals of reference indicate similar parts, Figure l is a perspective view of our said invention, showing the same in practical operation. Fig. 2 is an enlarged perspective view of the device itself, with only a portion of the handle shown. Fig. 3 is a plan view of the same; Fig. 4, a side elevation thereof, the dotted lines in said figure showing the positions assumed by the bisected portions of the cloth from the point of the cutting-knife. Fig. 5 is a fragmentary detail sectional view of the grooved Wheel 6 as looking in the direction indicated by the arrows on the line 5 5 in Fig. 6. Fig. 6 is a front elevation as looking in the direction indicated by the arrows on the line 6 6 in Fig. 4. Fig. 7 is a modified construction of our invention, showing how the grooved wheel and a cutting-knife could be employed at both ends thereof.

In the drawings, 1 is the frame or bed-plate, to which all the parts are connected.

2 are small antifriction-rollers that have their bearings in the bed-plate and are adapted to relieve the friction, as well as to overcome the irregularity that might occur in the floor.

3 and 4 are standards integral with the bedplate 1. Adjustably mounted at the top of the standard 3 is a fork'5, which carries the grooved wheel 6 at one'end and terminating into a shank at the other, to which the handle 14 is secured. The fork 5 is adjustably secured to the standard 3 by means of a bolt 7, which carries the wing-nut. By providing for this adjustment a variety of angles or pitches can be imparted to the fork 5 and the grooved wheel 6, thereby changing the relation of said wheel to the cutting edge on the knife, as well as changing the cutting-point of contact on the cutting edge. Thus when the edge has become worn at one point it may be shifted from time to time until the blade has been used throughout its entire length. There are other reasons that will be hereinafter more particularly described.

The grooved wheel 6' is swung on a trunnion in the fork 5 and rotates by the surface of the cloth coming into contact with its face. In the peripheral face of this wheel a groove 9 of any desired depth is cut. This groove is best shown in Figs. 3 and 6. The depth of groove 9 should not be less than the length of the cutting-blade, as the amount of insertion regulates the cutting-surface on the edge of the knife. The knife is made triangular, which gives it two cutting edges and increases its utility. The knife is mounted on a slide which is seated in a way 11 in the bed-plate. This slide has tapering sides, being widest at the bottom, which corresponds to the way 11 and insures it a firm seat. It will be seen that the knife can only be withdrawn in the manner in which it was inserted.

A standard 4, integral with the bed-plate, is situated in the rear of the cutting-knife 10 and is in line longitudinal therewith. Attached to the upper end thereof is a crossarm 12, carrying two separating antifriction-- rollers 13, the object of these rollers being to separate the edges of the bisected portions of the cloth, and thereby prevent any binding or pinching of the cloth which might retard the progress of cutting. This binding occurs when the edges of the cloth are allowed to assume the same position as they were before the cutting. It will be readily seen that these rollers perform in a mechanical manner the same function that is carried out in the old method of cutting by hand, in which one portion of the cloth is held in a raised position in the hand opposite the one employed in doing the cutting.

As previously stated, the cutting-knife 10 extends a short distance into the groove 9 in the peripheral face of the wheel 6. The knife being V-shaped, the cloth will naturally climb the incline during the operation until it reaches the surface of the wheel 6, when the said wheel rotates during the operation of propulsion. point where the knife-blade enters the groove 9, it will be seen that the blade at this point will soon become worn and unfit for use, while the other portion thereof would still be in condition for use. Therefore the object of adjustably mounting the wheel 6 is that it can be lowered or raised and Vary the amount of insertion of the cuttingblade into the groove 9, (see dotted position in Fig. 5,) and by gradually working in the opposite direction on the cutting edge from the end that might be selected the whole cutting edge is brought into use.

As will be noted by examining Fig. 6, the positions of the knife-blade 10 in relation to the edges that form the groove 9 a shearing of the cloth is obtained, which in turn imparts to the cloth a smooth clean-cut edge, which is the paramount object therein to be obtained.

In Fig. 7 we have'shown a grooved wheel and a cutting-knife located at both ends of As the cutting is all done at the Having thus fully described our said inven- I tion, what we desire to secure by Letters Patent is 1. In a device for cutting floor-cloths, linoleums, 850., the combination, with the bedplate 1, having antifriction-rollers mounted therein, a groove or way, having its greatest width at the bottom, out longitudinally in the surface of said plate, a slide, carrying the knife, secured in said groove, a centrally mounted standard 3, integral with the bedplate, a fork adjustably secured to the top thereof, a handle secured to one end thereof, a grooved wheel 6, mounted in the other, the said wheel being hung centrally over the knife in a latitudinal manner, but whose axis is slightly in advance of the top point of the cutting-knife on a perpendicular line, the

periphery of the wheel 6, being at all times at a less height, from the bed-plate, than the top point of the cutting-knife, substantially as shown and described.

2. In a device for cutting floor-cloths, linoleums, &c., the combination, with the bedplate, having a standard mounted directly in the rear of the cutting-knife and in a longitudinal line therewith, said standard carrying separating-rollers which act on the cloth, and

diverge the edges of the bisected cloth from the point of the cutter, substantially as described and for the purposes set forth.

3. In a device for cutting floor-cloths, linoleu ms, 850. the combination, with a bed-plate,

carrying a knife secured in a groove in each end thereof, a centrally-mounted standard integral therewith, a fork adj ustably secured to the top thereof, said fork carrying a grooved wheel at each end which overhang the cutter-knife, a handle adj ustably secured to the standard in such a manner as to allow it to be reversed from one end to the other, substantially as shown and for the purposes set forth. In witness whereof we have hereunto set our hands and seals, at Indianapolis, Indiana, this 23d day of January, A. D. 1899.
